It has been designed from the ground up for ease of maintenance and optimal bearing performance.\u003c\/p\u003e \u003cp\u003eHere are a few key points of the AC-2 BMX Front Hub: The AC-2 hubs use 20mm Angular Contact bearings with a wave spring pre-load. Bearings are pressed into tapered cups that mate with the angled bores machined into the hub shell. This design feature allows bearing\/cup to be easily installed and removed from hub shell without any special tools. No more presses or hammers needed!\u003c\/p\u003e \u003cp\u003eAnother attribute of the tapered bearing cup\/angled hub shell bore design is how the bearings seat in the hub. The bearings\/cups on each side of the hub shell are in perfect alignment with each other! This ensures superior bearing performance and less chance of premature wear.\u003c\/p\u003e \u003cp\u003eHub shell literally floats on the axle. The only force on the bearings is supplied by the wave spring (which delivers the appropriate bearing pre-load needed for angular contact bearings). Tightening of axle bolts has absolutely no affect on the bearings!\u003c\/p\u003e  \u003cp\u003eThe bearings, wave spring, and shim(s) are secured on the axle by one retaining ring. The only tool used to assemble\/disassemble the AC-2 hub is a pair of snap ring pliers!\u003c\/p\u003e   \u003cp\u003e\u003cspan\u003e###section###\u003c\/span\u003e\u003c\/p\u003e \u003ch5\u003e\u003cspan\u003eProduct Specs\u003c\/span\u003e\u003c\/h5\u003e \u003col\u003e \u003cli\u003e\n\u003cstrong\u003eAXLE SIZE\u003c\/strong\u003e: Female\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSPOKE HOLES\u003c\/strong\u003e: 36h\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBEARINGS\u003c\/strong\u003e: Angular contact\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eWEIGHT\u003c\/strong\u003e: 245g (8.64oz)\u003c\/li\u003e \u003c\/ol\u003e","brand":"Profile","offers":[{"title":"Red","offer_id":43007821676605,"sku":"ZZ00683","price":157.52,"currency_code":"USD","in_stock":false},{"title":"Green","offer_id":43007821709373,"sku":"ZZ00684","price":157.52,"currency_code":"USD","in_stock":false},{"title":"Blue","offer_id":43007821742141,"sku":"ZZ00682","price":157.52,"currency_code":"USD","in_stock":false},{"title":"Matt Black","offer_id":43007821774909,"sku":"ZZ00680","price":157.52,"currency_code":"USD","in_stock":false},{"title":"Gold","offer_id":43007821807677,"sku":"ZZ00685","price":157.52,"currency_code":"USD","in_stock":false},{"title":"Black","offer_id":43007821840445,"sku":"ZZ00679","price":157.52,"currency_code":"USD","in_stock":true},{"title":"Silver","offer_id":43007821873213,"sku":"ZZ00681","price":157.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0222\/8328\/8640\/files\/abdcb9b0-a592-4244-823f-e8cc47c13cdd.jpg?v=1771847487","url":"https:\/\/us.sourcebmx.com\/en-row\/products\/profile-ac-2-race-front-hub","provider":"Source BMX - US","version":"1.0","type":"link"}
